My SS is fly by wire... and I had a few tires break loose on me a few weeks ago.

I wanted to see what the stock 'verter flashes to. Stopped, held brake, punched the gas, and got some squealing. (it was a little wet out) It looked to be stalling at 1900-2000.

I *really* think that this is just the way the 5.3 behaves in a SUV. My Avalanche would only stall up to about 1700-1800, and would NEVER get the tires spinning in a brake-stand type manuever. Not even in the wet.

It may be different brake proportioning between the trucks and the SUV's.

 

My Tahoe is throttle by wire with a Intercooled Magnacharger,ASM header and Yank 3000.I don't have any problem hooking up on a dry street.At the track I turn off the traction control do a good burnout after wetting the tires,then I bring the revs up to 3000 rpm to induce tire spin,the converter flashes to about 3800 rpm on the launch,this results in consistant 1.80 60' times and very low 13 sec. 1/4 mile times.Traction is not really an issue.
